WATER GAIUGE.

, Application filed October 14, 195p. Serial No. 416,949.

To all whom it ay com-em:

'Be it known that I, ERNEST Now, a subject of the Dominion of Canada residing at Yorkton, in the Province of askatchewan and Dominion of Canada, have invented certain new and useful Im royements in Water Gauges, of which the ollowing is a specification.

My invention relates to improvements in water gauges for steam boilers, or the like, and has. particular reference to a Water, gauge having automatic means to shut ofl the passage of-the steam to the glass tube, when the tube breaks. 7

An im ortant object of the invention is to provi e a device of the above mentioned character, which is simple in construction, and automatic and reliable in operation.

In the accompanying drawings formin a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Fi re 1 is a central longitudinal sectiona view through a device embodying the invention, and,

Figure 2 is a plan 'view of the steam valve.

The numeral 5 designates an upper steam casing, having a flange 7 or web, dividing e same into upper and lower chambers 8 and 9. A laterally extending tube 10 leads into the upper chamber 8, and has a plug or valve body 11, pivoted therein, and adapted to close the same. The tube 10 has a flange 12, which is bolted to the boiler plate 13, as shown at 14..

The upper end of the casing 5 is reduced and screw threaded, as shown at 15, to engage a cap 16, having a longitudinal bore 17, and chamber 18. The bore 17 is closed by a plug 19.

A steam valve is provided, including a tubular body portion 20, slidable in an opening 21, in the flange 7. This tube has its lower end open and its upper end closed, as shown at 22. A disk valve 23 surrounds the tubular body portion 20, extending radially therefrom, at a point beneath and spaced from the closed end 22. This disk valve has apertures 2'1, 'andthe tubular body portion has apertures 25, which are covered by the wall of the bore 17 when the steam valve is shifted upwardly.

The numeral 26 designates a water casing, provided in its bottom with a drain opening, closed by a pin 27. This water casing has a flange 28, an upper and lower charnbers 29 and 30. The casing 26 is connec sd with a tube 31, secured to the boiler plate 13 by bolts 32. The numeral 33 designat-s the upper section of the water casing,

havcng screw-threaded engagement at 34., with the lower section 26. The lower end of the section 33 has a flange 35, provided with an opening 36, this flange forming a chamber 37.

Thenumeral 38 designates the tubular body portion of a water valve, slideble in the opening 36, and having apertures39. A disk valve 40 is secured to the lower end of the tubular body portion and projects radially therebeyond, and has apertures 41. The apertures 39 and 41 are covered when the water valve moves upwardly, as is ob vious. A valve body 42 is connected with the tube 31.

The numeral 43 designates a glass tube, the upper end of which projects into. the lower end of the casing 5, and is held there- .in b gland nut 44, engaging an iron ring 45, aving rubber packing 46 behind it. The lower end of the tube 43 extends into casing section 33 and is engaged by gland nut 47, engaging iron ring 48, in turn enga ing a rubber packin 49.

rom the fore oing escription, it is obvious that shpuld the glass tube 43 break, the steam passing through the opening 19 will quickly shift the steam valve upwardly by engaging the disk 23 thereon, covering apertures 25 by the walls of the bore 17, while the water will shift the water valve upwardly, so that the apertures 39 will be covered by the walls of the bore 36. The steam and water are therefore cut off and prevented from escaping out of the broken tube.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the sub joined claim.

Having thus described my invention, I claim:-

A water gauge adapted for connection to a steam boiler comprising a pair of spaced open ended valve casings, a gauge glass, means for securing said gauge glass to adja ,nt ends of the valve casings, means forming an upper and lower chamber in each valve casing including a hor'zwntrfl member having a for establishing conununication between said chambers, a valve romprisinq a disk having a sleeve secured to one m-e mama? and extending at right angles theretm said disk having ports adjacent its periphery and said skew having poms mar iis attachment is the disk, means for normally supporting said valves in spaced rdation from said horizontal member so that the shaves fiiezeof are slid:

able in the passage extending through fahr:

, whereby upon breakage of the 522.55 the valves are caused to move vertically in closed position thereby cutting in? remmuniratiuh lvetwm'n the upper and EOWBZ' (hammers in reach casing fln'uugh the goris in we valves.

In testimony wheresf, I have afiixed my s ignamre in the presrnc? of two witnesses.

ERNEST WUUD.
